I have done resizes many time with qm resize <vmid> <disk> <size> , always growing disks, now I have a situation with a VM (win 2012r2) that is behaving very slow, so I moved a lot of pieces to another VM and now I am left with a hard drive that used to be 400GB+ used to be only 25GB.

I already resized the hard drive in windows to the desired size (down from 500GB to 50GB)View attachment 9567

and would like to downsize also the disk size in Proxmox....

I've tested zfs-snapshots with samba and shadow_copy2 to access old file versions which are created with zfs-snapshots.
This work well on the host, but I don't want to use samba on the host directly.
But if I snapshot an container mount point, I can see inside the container the snapshots, but no content:

I'm trying to install windows server 2019 essential version on proxmox Virtual Environment 5.2-10. I tried to use drive virtio as harddisk, I used virtio-win-0.1.141.iso but does not recognize any drivers. Unfortunately disk ide or sata are not supported by windows server 2019. Can anyone help me, it's very urgent. Thank you to everyone.

I already have multiple container running in privileged mode.
I discovered the way to migrate into unprivileged with the backup and restore trick.

I have existing hand made template for debian 8 and 9. I'm not able to create CT in unprivileged but backup and restore trick still working.

I've setup up two no hosts in a new datacenter and tried to move LXCs from the old hosts via vzdump & ssh-pipe. This failed several times and I could break the problem down to `pct restore` from pipe:

Everything work fine, it's very reliable, but a problem occurs when a proxmox node crashes.

proxmox's HA moves the VMs from the node that crashes to other nodes, and start VMs. VMs are seen as started by proxmox, but rbd images are still locked on ceph side by the crashed node. So the VM stays in a state where it's disk is locked by another process, and fails to boot...

I'm running the latest version of Proxmox, 3.1, recently downloaded from the site.

When I boot the fresh installation up, I get the error eth0 not found

Any assistance would be great

Thanks

I've been doing some pre-production testing on my home server and ran into some kind of bottleneck with my storage performance, most notably on my optane drive.

When I install a Windows vm with the latest VirtIO drivers the performance is kinda dissapointing.
I've tried switching over from VirtIO to VirtIO SCSI and tried numerous different options.
Using LVM or ZFS does not give any different results either.

Finally I tried the same with a ramdisk, these gave me similar results to the...
